Detonation on a Tabletop

Abstract

Detonation on a tabletop refers to experimental studies in the Dlott group at the University of Illinois that involve using a pulsed laser to launch small hypervelocity flyer plates at tiny charges of various explosives while diagnostics with high time and space resolution probe the explosive response. There were four main thrust areas with corresponding publications listed below. These were: (1) Experimental advances; (2) Hot spots and detonations in plastic-bonded explosives (PBX); (3) Shocked reactive materials. The high points were: (1)Improved methods for temperature measurements; (2) Multimaterial simulations of laser-launched flyer plate launch and impact; (3) Tabletop detonations produced in nitromethane (NM) and NM with amine catalyst and visualization of novel cellular structures; (4) Hot spots dynamics in several PBX; (5) Hot spot dynamics visualized in single and poly crystals of HMX; (5) Fast energy release in reactive materials.
